Oxygen Sensor with Install Tool.
I have no complaints with this order. Everything matched and worked perfectly. This was a "downstream" Oxy Sensor that I ordered and the install tool was for the "upstream" sensor. No room to use it for this application. I just used an open end wrench to remove and replace the sensor. No problem. Would buy from 1A AUTO again.
